.To all whom, it may concern:

Be it known that I, WILLIAM A. PATTER soN, a citizen of-the United'States of America, residing at Pittsburg, in the county of Allegheny and State of. Pennsylvania, have invented certain new and useful Improvements in Telephone Attachments, of which Q the following is a specification, reference being had therein to the accompanying drawin s.

This invention relates to certain new and useful improvements in telephone attach- .adapted .to fit over the mouthpiece of the J transmitter of a telephone, and in the-hood I provide an opening which is closed by a shutter. When a person is receiving a message over a telephone and not conversing, the

. shutter is adapted to be closed to exclude all ing noises and conversations that may occur in the vicinity of the telephone from passing through the same.

The construction of my improved attachment will be hereinafter more fully described .and then claimed, and, referring-to the draw ings accompanying this application, like numerals of reference' designate correspondplarts throughout the several views, in who 4 Figure 1 is a side elevation of the ,telephone-transmitter equipped with my improved attachment. Fig. 2 is a front elevation of the same. Fig. 3 is a vertical sectional view of the transmitter equipped with the attachment. Fig. 4 is a rear elevation of the attachment. Fig. .5 is a plan of the shut- Fig. 6 is a front elevation of the attach:

' ment with the shutter thereof in an openposition.

In the.accom anying drawings the reference-nume'ral 1 esignates the-end of a transmitter having a funnel-shaped mouth iece 2.

M inventlon resides in providing 1:, e fun nel-sliaped mouthpiece 2 with an attachment comprising an annular plate or disk 3, having a peripheral flange 4." The plate ordisk 3 circular disk havin rivet 6, a shutter 7. The body portion of the shutter is substantially circular in plan and is provided with an operating-lever 8 and a lug 9, by which it is pivotally mounted upon the plate or disk 3., The plate or disk 3 is'adapted to fit snugly upon the funnel-shaped mouthpiece 2, and the central o ening 5 thereof is adapted to horizontally a he with the openings of the transmitter. The plate or' disk3 is provided with a lu 0r pin 10, adapted to limit the movement 0 the shutter 7 and determine the closure of'the opening 5 of the disk 3; As heretofore stated, when a person is receiving a message over the telephone and is not conversing the shutter 7 is adapted to be closed, entirely excluding all noises or conversations from transmitter.

ment of strong and dura le metal, such as brass or bronze, the metal being olished to conform with the metallic mountmgs of the telephone and enhance the general appearanceof the same.

It will be noted that various changes may be made in the details of construction without departing from the spirit of the inventlon or sacrificing any ofthe advantages thereof. What I claim, and'desire to secure by Letters Patent, is"- The combination with a telephone-transmitter having a circular trumpet-mouth, of a, an integral annular flange adapted to- 'ctionally engage the outer. edge of the 'trum et-mouth of the transmitter, said disk having a circular central opening of less size than the opening in the smaller end of the trum et-mouth-of the transmitter, a shutter of sufi lar form larger in diameter than the central opening in said disk, said shutter having a passing into the stantially circuprojectlon at one side pivotally attached to a said disk and a rojection at the .dia'metrically-o posite side extending be ond the ed e of t e'disk and constituting a andle.

testimony whereof I aflix my signature in the presence of two witnesses. 1
